Evaluation of the trauma-specific frailty index in geriatric trauma patients according to the new World Health Organization age classification.

OBJECTIVE: We compared the 15-variable trauma-specific frailty index and traditional injury scoring systems to determine trauma severity and predict discharge disposition in geriatric trauma patients based on the old and new World Health Organization age classifications. METHODS: This prospective, observational, single-center study included geriatric patients aged ≥65 years with blunt trauma. We categorized patients as elderly based on the old or new World Health Organization age classification into group I (aged 65-79 years) and group II (aged ≥a80 years), respectively. At admission, we used traditional injury scoring systems (e.g., the Glasgow coma scale, injury severity score, and revised trauma score) to determine trauma severity. We compared the Trauma-Specific Frailty Index and traditional injury scoring systems between the patient groups and evaluated them for correlations. RESULTS: We included 169 geriatric patients (80 and 89 in groups I and II, respectively). The mean Trauma-Specific Frailty Index score was significantly higher among females than males (p=0.025) and group II than group I (p=0.021). No significant correlations were observed in terms of the Trauma-Specific Frailty Index and traditional injury scoring systems in both groups. The mean Trauma-Specific Frailty Index score was significantly different between the hospitalized and discharged patients in group I (p=0.005), but not in group II (p=0.526). CONCLUSION: The 15-variable Trauma-Specific Frailty Index score is superior to traditional injury scoring systems for managing and predicting discharge disposition in geriatric trauma patients aged 65-79 years.

Relationship between measures of thoracic diameter and cardiopulmonary resuscitation-induced thoracoabdominal injury.

OBJECTIVE: We investigated the relationship between thoracic diameters and chest compression-related thoracoabdominal injury in patients with non-traumatic out-of-hospital cardiac arrest who had a return of spontaneous circulation after cardiopulmonary resuscitation. METHODS: A total of 63 consecutive adult non-traumatic out-of-hospital cardiac arrest patients were enrolled in this prospective study. Computed tomography was performed on each patient and the anteroposterior diameter, skin-to-skin anteroposterior diameter, and transverse diameter of the chest were measured. Patients were divided into two groups based on the presence or absence of cardiopulmonary resuscitation-related thoracoabdominal injury. Age, sex, and duration of cardiopulmonary resuscitation, anteroposterior diameter, skin-to-skin anteroposterior diameter, and transverse diameter were compared between the groups. The primary outcome was the relationship between thoracic diameters and cardiopulmonary resuscitation-induced thoracoabdominal injuries. RESULTS: Thoracoabdominal injuries were detected in 46% (n=29) of the patients and consisted of rib fractures in 22 (34.9%) patients, pulmonary contusion in 7 (11.1%), and sternal fracture in 3 (4.8%) patients. There were no significant differences in cardiopulmonary resuscitation duration between patients with and without thoracoabdominal injuries (p=0.539). Similarly, there were no significant differences in anteroposterior diameter, skin-to-skin anteroposterior diameter, or transverse diameter between patient groups (p=0.978, p=0.730, and p=0.146, respectively) or between patients who died within the first 28 days and those who survived for longer than 28 days (p=0.488, p=0.878, and p=0.853, respectively). CONCLUSION: The iatrogenic thoracoabdominal injuries caused by cardiopulmonary resuscitation performed according to the cardiopulmonary resuscitation guidelines were independent of thoracic diameters. Therefore, the cardiac compression depth of 5-6 cm recommended by the current cardiopulmonary resuscitation guidelines is reliable for patients with different thoracic diameters.

The utility of serum miRNA-93 and miRNA-191 levels for determining injury severity in adults with multiple blunt trauma.

BACKGROUND: Various scoring systems have been developed to determine the trauma severity and prognosis of patients following multiple blunt trauma (MBT). However, these scoring systems do not provide exactly the desired severity assessment. In recent years, serum concentration of many specific microRNAs (miRNAs), especially for head trauma, has been shown to play an important role in determining the diagnosis, severity, and prognosis of injury. To date, however, no studies have investigated serum miRNAs in patients with MBT. Thus, this study measured the expression of miRNA-93 and -191 in the serum of adults with MBT and examined the correlations of Injury Severity Score (ISS) and Revised Trauma Score values with serum miRNA-93 and -191 levels in these patients with the aim of predicting trauma severity based on the miRNA levels. METHODS: This prospective case-control study enrolled 50 consecutive adults with MBT and age- and sex-matched 60 healthy controls. The patients were divided into ISS >16 (Group 1, major or severe trauma) and ISS ≤16 (Group 2, minor or mild-moderate trauma) groups. Serum miRNA-93 and -191 levels were assessed using quantitative real-time reverse transcription-PCR. We evaluated whether the miRNAs were differentially expressed in major and minor MBT patients and determined their utility for assessing the severity of injury. RESULTS: The mean serum miRNA-93 and -191 levels were significantly elevated in the patients compared to the controls and were higher in patients with ISS >16 compared to those with ISS ≤16, although the difference was not significant. In the patients with multitrauma, ISS was significantly, negative and weak correlated with serum miRNA-191 level (rho=-0.320, p=0.023) but not with the serum miRNA-93 level. No optimal cutoff for the serum miRNA-93 level was found with respect to trauma severity (AUC 0.617, [0.455-0.779]). However, an optimal cutoff value for serum miRNA-191 was identified, with values <1.94 indicating severe trauma (AUC 0.668 [0.511-0.826]; 65.6% sensitivity, 77.8% specificity). CONCLUSION: miRNA-191 and -93 levels were significantly upregulated in multitrauma patients compared to controls. The level of miRNA-191 in conjunction with ISS, but not that of miRNA-93, may be a useful biomarker for determining injury severity in patients with multitrauma.

Safety and efficacy of hydroxychloroquine in 152 outpatients with confirmed COVID-19: A pilot observational study.

PURPOSE: We investigated the efficacy and safety of hydroxychloroquine for empirical treatment of outpatients with confirmed COVID-19. METHODS: In this prospective, single-center study, we enrolled ambulatory outpatients with COVID-19 confirmed by a molecular method who received hydroxychloroquine. The patients were divided into low- and moderate-risk groups based on the Tisdale risk score for drug-associated QT prolongation, and the QT interval was corrected for heart rate using the Bazett formula (QTc). The QTc interval was measured by electrocardiography both pretreatment (QTc1) and 4 h after the administration of hydroxychloroquine (QTc2). The difference between the QTc1 and QTc2 intervals was defined as the ΔQTc. The QTc1 and QTc2 intervals and ΔQTc values were compared between the two risk groups. RESULTS: The median and interquartile range (IQR) age of the patients was 47.0 (36.2-62) years, and there were 78 men and 74 women. The median (IQR) QTc1 interval lengthened from 425.0 (407.2-425.0) to 430.0 (QTc2; 412.0-443.0) milliseconds (ms). However, this was not considered an increased risk of ventricular tachycardia associated with a prolonged QTc interval requiring drug discontinuation, because none of the patients had a ΔQTc of >60 ms or a QTc2 of >500 ms. Moreover, the median (quartiles; minimum-maximum) ΔQTc value was higher in patients in the moderate-risk group than those in the low-risk group (10.0 [-4.0-18.0; -75.0-51.0] vs. 7.0 [-10.5-23.5; -53.0-59.0 ms]) (p = 0.996). Clinical improvement was noted in 91.4% of the patients, the exceptions being 13 patients who presented with non-serious adverse drug reactions or who had severe COVID-19 and were hospitalized. Adverse effects related to hydroxychloroquine were non-serious and occurred in 52.8% (n = 80) of the patients. CONCLUSIONS: Our findings show that hydroxychloroquine is safe for COVID-19 and not associated with a risk of ventricular arrhythmia due to drug-induced QTc interval prolongation. Additionally, hydroxychloroquine was well tolerated, and there were no drug-related non-serious adverse events leading to treatment discontinuation in the majority of patients who were stable and did not require hospitalization.

The value of the inferior vena cava ultrasound in the decision to hospitalise in patients with acute decompensated heart failure; the best sonographic measurement method?

OBJECTIVES: The primary aim of this study was to determine the value of the inferior vena cava (IVC) ultrasound in the decision to hospitalise acute decompensated heart failure (ADHF) patients. Our secondary aim was to find the most successful IVC measurement method in monitoring volume status. METHODS: ADHF patients were accepted over a 1-year period in this study. Patients' vital signs, laboratory tests and IVC measurements measured by six methods (in B- and M-mode; maximum, minimum diameter and caval index) performed on an hourly basis were recorded. The presence of any statistically significant difference between the IVC measurement methods, laboratory tests and vital parameters between the hospitalised and discharged patients was calculated. ROC curves were produced in order to determine the ability of parameters to differentiate two groups. Spearman's correlation test was used to investigate correlation between the IVC measurement methods and patients' urine outputs. RESULTS: A total of 71 patients were included in the study; 42 of these were hospitalised and 29 were discharged. Potassium, brain natriuretic peptide, respiration rate, urine output, maximum and minimum IVC diameters differed significantly between the two groups. Minimum IVC diameter measured in M-mode was identified as a weak marker with 65% sensitivity and 64% specificity (+PPV: 73%; -NPV:54%) for hospitalisation. Change in maximum IVC diameter measured in B-mode exhibited a high degree of correlation with change in body fluid (cc: 0.802). CONCLUSION: IVC ultrasound may have a limited value in the decision to hospitalise ADHF patients. But Maximum IVC diameter may be an ideal method for monitoring hypervolemic patients' volume status.

Serum Copeptin Levels Predict the Return of Spontaneous Circulation and the Short-Term Prognosis of Patients with Out-of-Hospital Cardiac Arrest: A Randomized Control Study.

INTRODUCTION: Early and accurate prediction of survival to hospital discharge following resuscitation after cardiac arrest (CA) is a major challenge. Biomarkers can be used for early and accurate prediction of survival and prognosis following resuscitation after CA, but none of those identified so far are sufficient by themselves. HYPOTHESIS/PROBLEM: The goal of this study was to investigate the predictive power of the serum copeptin level for determining the return of spontaneous circulation (ROSC) and prognosis of patients with non-traumatic out-of-hospital cardiac arrest (OHCA) who underwent cardiopulmonary resuscitation (CPR). METHODS: A total of 76 consecutive consenting adult patients who were diagnosed as non-traumatic OHCA and 63 age- and sex-matched healthy controls were enrolled. The patients were divided into two groups based on whether or not they had ROSC. The ROSC group was divided into two sub-groups according to whether death occurred within 24 hours or after 24 hours following ROSC. Serum copeptin, high-sensitivity cardiac troponin (hs-cTnI), creatine kinase-muscle/brain (CK-MB), glucose, and blood gas values were compared between the groups. RESULTS: Serum copeptin levels were significantly higher in the patient group than control group (P <.001). Receiving operator characteristic analysis revealed a cut-off copeptin level of 27.29pmol/L, with 98.7% sensitivity and 100.0% specificity, for distinguishing patients from controls. Serum copeptin levels were significantly lower in the ROSC group than non-ROSC group (P = .018). Additionally, the mean serum hs-cTnI level was significantly higher in the ROSC group than non-ROSC group (P = .032). However, there were no significant differences in the mean serum glucose level and CK-MB levels or arterial blood gas levels between the ROSC and non-ROSC groups (all P >.05).Ten (38.5%) of the patients died within the first 24 hours after ROSC, whereas 16 (61.5%) survived longer than 24 hours. Serum copeptin levels were significantly lower in patients who survived longer than 24 hours compared with those who died within the first 24 hours. Moreover, the mean CPR duration was significantly lower in patients surviving more than 24 hours compared with less than 24 hours. CONCLUSION: The serum copeptin level may serve as a guide in diagnostic decision making to predict ROSC in patients undergoing CPR and determining the short-term prognosis of patients with ROSC.

Plasma oxidative-stress parameters and prolidase activity in patients with various causes of abdominal pain.

PURPOSE: We aimed to investigate the predictive power of plasma prolidase activity and oxidative-stress parameters for distinguishing in patients with various causes of non-traumatic abdominal pain who presented to the emergency department. METHODS: This study enrolled 100 consecutive adult patients and 100 age- and sex-matched healthy controls. The patients were divided into surgically treated patients (STP); medically treated patients (MTP) and nonspecific abdominal pain (NSAP) patients. As predictors of early oxidative changes, the plasma prolidase activity, total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI) were assessed using a novel automated method. RESULTS: No significant difference was observed between the patients and the controls with respect to age or sex (p = 0.837 and 0.188, respectively). The plasma TOS, OSI value, and prolidase activity were significantly higher in the patients with abdominal pain than in the controls (p < 0.001, p = 0.001, and p < 0.001, respectively); however, there was no significant difference in the TAS (p = 0.211). The mean plasma TOS, OSI value, and prolidase activity differed significantly among the three groups (p < 0.001, p = 0.001, and p < 0.001, respectively). The STP had the highest TOS and prolidase activity. However, there was no significant difference in the mean plasma TAS in either group of patients (p = 0.419). CONCLUSION: The plasma prolidase activity and TOS level, as biomarkers of oxidative stress, enable discrimination of patients with NSAP from those with surgical abdominal pain that requires emergent surgical treatment.

A new side effect of synthetic cannabinoid use by the bucket (waterpipe) method: Acute respiratory distress syndrome (ARDS).

The use and content of synthetic canibinden (SCs) has been rapidly increased in the last decades. The complex content of these substances bring along a wide spectrum of side effects. In addition to the expected neuropsychological side effects of pleasure-inducing substances such as agitation, anxiety, panic attack and hallucinations, rare cases of cerebrovascular diseases, seizures, acute renal injury, myocardial infarction and chronic lung injury have also been previously reported. Here we report a 19-year -old male who was presented with acute respiratory distress syndrome (ARDS) within hours of inhaled SC use with the rarely preferred bucket method. There is limited information in the literature about pulmonary effects of SCs and we could not detect any other ARDS case that develoed within hours after consumption of SC with the bucket method.

A young puerperal woman presenting to emergency department with severe dyspnea.

Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy presenting with heart failure (HF) secondary to left ventricular systolic dysfunction towards the end of pregnancy or in the months following delivery, where no other cause of HF is found. The symptoms and signs of this rare disorder mimic those of the physiological changes of pregnancy or other cardiovascular diseases. Consequently, its diagnosis is frequently delayed, which worsens an already poor prognosis. Here, we report a young adult who was diagnosed with PPCM, early, with the help of focused cardiac ultrasonography, performed after presenting to the emergency department with nonspecific respiratory complaints, including dyspnea and hemoptysis, which suggested at first pulmonary embolism.
